Title: A calendar ring drive and date setting mechanism for a calendar timepiece
IPC: G04B19/253
Filed: 1967-10-02
Abstract: 1,205,963. Calender timepieces. HAMILTON WATCH CO. Oct. 2, 1967 7 [Nov. 10, 1966], No.21451/70. Divided out of 1,205,962. Heading G3T. In a calender ring drive and date setting mechanism for a calender timepiece a calender ring is continuously driven from the dial train via a slip clutch, and means is provided for coupling a setting stem to the calender ring whereby the ring is adjustable by rotation of the stem. The calender ring 30 is driven continuously by a pinion 112 integral with a triangular cam 114 and a staff 110, the cam 114 being engaged by a spring 118 secured to a toothed wheel 116 rotatable on the staff 110 and driven by the dial train. The cam 114 and the spring 118 constitute a slip clutch, and during the setting of the calender ring 30 by a setting wheel 64, actuated by rotations of a stem 26, the pinion 112 and the cam 114 rotate relatively to the spring 118 and the wheel 116 so that the dial train is not affected. Alternatively the slip clutch may be formed by a conical surface 136, Fig.4 (not shown) an the pinion staff 110 engaged in a similarly shaped hole in the hub of the wheel 116.

Title: Improvements in change speed gear
IPC: F16H3/12
Filed: 1925-08-27
Abstract: 261,488. Wolseley Motors, Ltd., and Boden, O. Aug. 29, 1925. Facilitating changing speed. - Relates to change-speed gearing for vehicles of the kind in which changes are effected by sliding toothed wheels into mesh and in which such changes. are facilitated by the use of auxiliary gearing to speed up the wheels about to be unmeshed. The clutching of the respection wheels of the auxiliary train such as G, K is effected by means which are struck or directly moved by the main gear such as C about to be unmeshed. Thus A is the driven shaft of the gearing which can be clutched to an aligned driving-shaft, not shown, or driven at reduced speeds through gears such as D fixed on a lay shaft B. When the splined gear C is tthrust towards its mating gear D, it strikes directly the inclined ends n of the rods N which pass through intervening mechanism E and abut against a splined friction cone H. The loose gear G of the auxiliary train is gripped between the cone H and a dog-faced disc M, Fig. 4, fast upon an extension b of the shaft A. The engine clutch being disengaged, the lay shaft is then driven through the pair G, K so as to bring the speed of the teeth of gear D to the proper speed to be picked up by the gear C without shock. Further displacement of the gear C causes it to ride freely over the ends of the rods N, which are pressed inwards against springs Q. Like provision may be made for the engagement of gears for other speeds.

Title: Methods of and arrangements for the digital control of operaing functions
IPC: H03J9/04
Filed: 1973-05-07
Abstract: 1429681 Remote control INTERNATIONAL STANDARD ELECTRIC CORP 7 May 1973 [13 May 1972] 21573/73 Heading G4H [Also in Division H3] A command signal receiver responsive to ultrasonic signals comprises a circuit 2, Fig. 2, which resonates at each command frequency in turn so as to generate a signal whose time of occurrence corresponds to the frequency received, and means for directing the generated signal on to one of a plurality of output control lines a-h, Fig. 7.  The command signals may be fed to "function registers" 19-23 as in the radio or TV controller of Specification 1,396,417, wherein one pulse (V or V<SP>11</SP>) represents a "forward" or "up" control step and an (N-1)-pulse burst (R) represents a "backward" or "down" control step. The receiver is controlled by a 1600 Hz multivibrator 4, Fig. 4, and a frequency divider 5-10 producing binary clock pulses A-G. Pulses E-G are used to switch combinations of capacitors C1-C3 into circuit 2 (10 msec. per combination) so as to produce an 80 msec. scan of eight frequencies in the 45 kHz region (Figs. 5, 8, not shown). Pulses E-G also address the rows of a diode matrix 14, Fig. 7. When the scan reaches the input frequency, the rise in voltage U 2  at the output of circuit 2 is detected by a circuit 3 which produces a 10 msec. 0-level pulse AS (all significant pulses are 0-level). Pulse AS and pulses B-D are combined in the circuit of Fig. 9 (not shown) to produce an 8À75 msec. pulse V which is fed to a mains control circuit 15-17, Fig. 7. A 1À25 msec. delay is imposed on V and pulses V<SP>11</SP>, R derived therefrom to avoid "ghost" pulses which could cause spurious command signals on lines a-h. Pulse V (occurring every 80 msec. scan) is applied to an OR-gate 41, Fig. 11 (not shown) which recives a pulse V<SP>1</SP> to produce a pulse V<SP>11</SP> as shown in Fig. 12 (pulse AS being produced in the 5th 10 msec. scan). Pulse V<SP>11</SP> is combined in an OR-gate 42, Fig. 13 (not shown) with clock pulses A: since pulse V<SP>11</SP> lasts for 8À75 msec. (same length as V), seven pulses R are produced. Pulse V<SP>11</SP> and pulse-train R are fed to respective columns of matrix 14: since all the signals are 0-level, the diodes act as OR-gates to produce a 0-level output on one of lines a-h which, for pulse V<SP>11</SP>, is inverted at 18-24.

Title: Improvements in or relating to electron discharge devices
IPC: H01J29/52
Filed: 1939-07-28
Abstract: 534,215. Cathode-ray tubes. KLEMPERER, O. July 28, 1939, No. 21913. [Class 39 (i)] In a cathode-ray tube wherein a cross-over in the beam is obtained by a modulating electrode which is biased to zero or negative potential, the change in axial position of the crossover due to the modulation is substantially compensated by an electron lens of the saddle field type which focuses the cross over B on the screen. The first electrode L1 is at a high positive potential to accelerate the beam from the cathode ; the second L2 is at a lower potential to decelerate the beam and form a space charge in the region of the lens ; the third L3 is at a high positive potential. As examples (i) the first and third are maintained at three kilovolts and the middle one at one kilovolt (ii) the first is at three, the second at two and the third at five kilovolts. The modulating electrode at the cathode varies the electron current in the beam and this variation acting through the space charge and the lens varies the focal length of the lens and thus compensates for the shift of the first cross over. The potentials in (i) may overcompensate the shift due to the modulating electrode ; this can be negatived by making the central electrode L2 long. Electrodes of diaphragm form may be used-instead of tubular electrodes-to handle beams of larger diameter. Specifications 470,004 and 505,751 are referred to.

Abstract: 220,606. Steffens, J. A. Aug. 16, 1923, [Convention date]. Alcoholic liquids, glycols. &c., distilling. - In dehydrating alcohol by distilling it in presence of ether, petroleum, benzol or other liquid immiscible with water, so as to obtain a residue of dehydrated alcohol, and a distillate which separates into two layers, the distillate is maintained at about the temperature of the still head, and the whole of the upper layer and about twothirds of the lower layer are returned to the still. The remainder of the lower layer is withdrawn and may be treated in a separate still to separate alcohol and benzol from the water. Aqueous alcohol is supplied to a column still 1 containing benzol by an inlet 5. Dehydrated alcohol passes from the base by an outlet 2. Vapours pass from the top of the still to a reflux condenser 13 which returns the condensate at about the temperature of the still head to a separating chamber 7 formed in the head or consisting of an heat-insulated chamber communicating with the head. A part of the lower layer of liquid is withdrawn through an outlet 10, and the upper layer and the remainder of the lower layer are returned to the still by an overflow pipe 8. Alcohol and benzol separated from the liquid which is withdrawn may be returned through inlets 16. The process is applicable also to the separation of water from propyl or butyl alcohols or glycols.
